    <p>How does your .NET Webservice look like?</p> <p>I had the same effect using <a href="http://code.google.com/p/ksoap2-android/" rel="noreferrer">ksoap 2.3 from code.google.com</a>. I followed the tutorial on <a href="http://www.codeproject.com/KB/webservices/CallWebServiceFromkSOAP.aspx" rel="noreferrer">The Code Project</a> (which is great BTW.)</p> <p>And everytime I used</p> <pre><code> Integer result = (Integer)envelope.getResponse(); </code></pre> <p>to get the result of a my webservice (regardless of the type, I tried Object, String, int) I ran into the <code>org.ksoap2.serialization.SoapPrimitive</code> exception.</p> <p>I found a solution (workaround). The first thing I had to do was to remove the "SoapRpcMethod() attribute from my webservice methods.</p> <pre><code> [SoapRpcMethod(), WebMethod] public Object GetInteger1(int i) { // android device will throw exception return 0; } [WebMethod] public Object GetInteger2(int i) { // android device will get the value return 0; } </code></pre> <p>Then I changed my Android code to:</p> <pre><code> SoapPrimitive result = (SoapPrimitive)envelope.getResponse(); </code></pre> <p>However, I get a SoapPrimitive object, which has a "value" filed that is private. Luckily the value is passed through the <code>toString()</code> method, so I use <code>Integer.parseInt(result.toString())</code> to get my value, which is enough for me, because I don't have any complex types that I need to get from my Web service.</p> <p>Here is the full source:</p> <pre><code>private static final String SOAP_ACTION = "http://tempuri.org/GetInteger2"; private static final String METHOD_NAME = "GetInteger2"; private static final String NAMESPACE = "http://tempuri.org/"; private static final String URL = "http://10.0.2.2:4711/Service1.asmx"; public int GetInteger2() throws IOException, XmlPullParserException { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); PropertyInfo pi = new PropertyInfo(); pi.setName("i"); pi.setValue(123); request.addProperty(pi); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL); androidHttpTransport.call(SOAP_ACTION, envelope); SoapPrimitive result = (SoapPrimitive)envelope.getResponse(); return Integer.parseInt(result.toString()); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
